方法：选择我院2010-01/2014-12收治的180例207眼新生儿泪囊炎患儿作为研究对象，按月龄分组，即<3月龄组(41例45眼)、3～6月龄组(75例91眼)、6～12月龄组(64例71眼)，分别给予泪囊按摩联合抗生素、泪道加压冲洗、鼻泪管探通等治疗，比较不同月龄新生儿泪囊炎治疗效果，统计治愈率，记录其治疗平均次数，总结治疗最佳时机。

结果：(1)不同月龄患儿均以Hasner瓣阻塞常见，所占比例高于鼻泪管骨性部位阻塞(P<0.05)，6～12月龄组鼻泪管骨性部位阻塞比例高于<3月龄组与3～6月龄组(P<0.05)，Hasner瓣阻塞比例低于<3月龄组与3～6月龄组(P<0.05)；(2)<3月龄组治愈眼数高于3～6月龄组与6～12月龄组(P<0.05)，3～6月龄组治愈眼数高于6～12月龄组(P<0.05)；(3)<3月龄组、6～12月龄组泪道冲洗有效率相近，均低于3～6月龄组，对比差异有统计学意义(P<0.05)；(4)三组患儿鼻泪管探通术治疗有效率均高于90%，对比差异无统计学意义(P>0.05)；(5)3～6月龄组、6～12月龄组治疗次数多于<3月龄组(P<0.05)，6～12月龄组治疗次数多于3～6月龄组(P<0.05)。

结论：对<3月龄泪囊炎患儿应首选泪道按摩保守治疗，无效者再予泪道冲洗及探通； 对3～6月龄患儿首选泪道冲洗； 对6～12月龄患儿则多建议予鼻泪管探通术处理。

METHODS: A total of 180 children(207 eyes)with dacryocystitis who were admitted to our hospital between Jan. 2010 and Dec. 2014 were selected as the study subjects. According to months of age, they were divided into <3 months old group(n=41, 45 eyes), 3-6 months old group(n=75, 91 eyes)and 6-12 months old group(n=64, 71 eyes). Three groups were respectively treated with lacrimal massage combined with antibiotics, lacrimal duct washing with pressure and lacrimal duct probing, etc. The curative effect was compared between different months old children with dacryocystitis. The cure rate was statistically analyzed. The mean times of treatment was recorded and the best time for treatment was summarized.

RESULTS: 1)Hasner valvular obstruction was common in different months old children, and the proportion was higher than that of children with nasolacrimal duct bony part obstruction(P<0.05). The proportion of children with nasolacrimal duct bony part obstruction in 6-12 months old group was higher than that in <3 months old group and that in 3-6 months old group(P < 0.05). The proportion of children with Hasner valvular obstruction was lower than that in <3 months old group and that in 3-6 months old group(P<0.05); 2)the number of cured eyes in < 3 months old group was higher than that in 3-6 months old group and that in 6-12 months old group(P<0.05), and the number of cures eyes in 3-6 months old group was higher than that in 6-12 months old group(P<0.05); 3)the effective rates of lacrimal duct washing with pressure in <3 months old group and 6-12 months old group were similar, lower than that in 3-6 months old group(P<0.05); 4)the effective rates of lacrimal duct probing in the three group were higher than 90%(P>0.05); 5)the times of treatment in 3-6 months old group and 6-12 months old group was more than that in <3 months old group(P<0.05), and that in 6-12 months old group was more than that in 3-6 months old group(P < 0.05).

CONCLUSION: For <3 months old children with dacryocystitis, conservative treatment like lacrimal massage should be preferred. For children without effect, lacrimal duct washing with pressure and lacrimal duct probing should be given; For 3-6 months old children, lacrimal duct washing with pressure is preferred, and for 6-12 months old children, lacrimal duct probing is recommended.
